“Steady Ed” Headrick invented the frisbee in the 1950s, then went on to create the sport of disc golf in the 1970s. “He lived for frisbee,” his wife said of the inventor of the classic American toy.

Another animal with surprisingly high kill rates? Domestic cats, which kill more than 30 percent of their targets.

Olympus Mons: Giant Mountain of Mars, rises three times higher than Earth's highest mountain, Mount Everest, whose peak is 5.5 miles above sea level.

Excessive sweating can lead to focus problems and slower reflexes, which is just one of the factors that makes this sport so dangerous.
